NCR RealScan 7882 Installation and Owner Guide

Step 2 - Setting Program

Parameters and Verifying Host

Connection

Now you need to turn on the NCR RealScan 7882. After making any necessary program changes, scan a few tags to verify that the RealScan 7882 is communicating with the host terminal.

Turning on the RealScan 7882

The RealScan 7882 does not have an On/Off switch. Use the circuit breaker switch in the checkstand that supplies power to the unit as the On/Off switch. Put this switch in the On position.

Programming the Communication Parameters

Caution: Some host terminals can corrupt the RealScan 7882 program if they are running and are connected to the RealScan 7882 while you are making program changes. Either turn off the host terminal or disconnect the interface cable before scanning any programming tags.

If the Interface Cable is provided as a kit rather than being included with the RealScan 7882, you can set the communication parameters by scanning the bar code on the label on the cable package. Standard defaults are set for most RS-232 or OCIA cables. If the cable is for a specific host terminal, all the necessary parameters required for that host terminal are set. The bar code label on the Interface Cable package must be the first bar code scanned after applying power to the RealScan 7882.

If the Interface Cable came with the RealScan 7882, the communication parameters are probably correct and you should not need to make any changes to these parameters. However, if the RealScan 7882 does not communicate with the host terminal, scan the appropriate tag from the following set of communication protocol tags.

Note: When scanning bar codes on the following pages, be sure to completely cover all bar codes except the one you are scanning.
